<!-- BEGIN DESCRIPTION -->
<div>   This module is an implementation of Secondary organic aerosols (SOA)
   from anthropogenic activities, and is based on Tie et al. (JGR, 2003).
   The only souce of SOA is due to the oxydation of C4H10 by OH.
   The concentrations of these 2 gas species are read as input. </div>

   To save space only the actual month is kept in memory which implies
   that the "atmos_SOA_init" should be executed at the begining of each
   month. In other words, the script should not run more than 1 month
   without a restart </dd>
